DAVID C. BAUGHMAN, OF ALBION, INDIANA.

RAILROAD-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 268,983,, dated December 12, 1882.

Application filed February 15, 1882. (No model.) 7

To all whom "it may concern;

Be it known that I, DAVID C. BAUGHMAN, of Albion, in the county of Noble and State of Indiana, have invented a new'and 1m proved Railroad-Signal, of which 'the following is a fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal elevation of my improved railroad-signal. Fig. 2 is a longitudinal sectional elevation of the end of the tubular arm. Fig. 3 is an inverted sectional plan view of the end of the tubular arm, on the line as .00, Fig. 1. a

A tubular arm or bracket, A, projects from the signal-house or from some other suitable standard, and is provided at its outer end with a vertical journal box, 0, adapted to receive thejournal D of a carrier or disk, E, carrying two signal-wings, F, and a removable signallantern, G, between these wings. Ashaft, H, extends longitudinally through the tubular arm A, and is suitably journaled in the same. The outer end of the shaft H projects from the end of the arm A, and on this'end of the shaft is mounted a cog-wheel, J, engaging with a quadrant-rack, K, on the under side of the disk or carrier E. A tooth, L, projecting from the bottom of the, carrier E, passes into a quadrant-recess, M, in the upper edge of the journal-box G. The journalD, which is made hollow ortubular, is provided in opposite sides with two horizontal slots, N, through which the shaft H passes, these slots being of such size asto permit a quarter-rotation of the journal D only, as will be described hereinafter.

On the inner end of the shaft H a grooved pulley, O, or asprocketwheel, is mounted, over which an overbalancing chain, P, passes, having weights Q Q? attached to the ends. One of these weights, Q ,is colored red, and the other, Q, is colored white. The signal-win gs F are colored red, and those sides of the lamp G that are parallel with the wings are colored red and are provided with colored lenses R. The other two sides of the lantern, which are at right angles to the wings, are colored white, and are provided with plain lenses R. The wings Fare attached to arms F, attach ed to the carrier or disk E, and the wings are located such a distance apart that the lantern G can be placed between them. The bottom of the lantern is provided with an aperture, T, which fits directly over the aperture W in the top of thejournal D, so that the air can pass through the tubular arm A and the hollow journal D into the lantern. Thereby I prevent the lantern from being extinguished by gusts of wind as the air that passes into the lantern is taken from the inside of the signal-house.

The operation is as follows: If the shaltH is rotated, the cog-wheel J ,engaging with the rack K, rotates the signal-carrier E. When the wings F and the lantern G are in the position shown the signal-wings are at right angles to the rails. By a quarter-rotation of the disk E the wings F are brought in-a position parallel with the rails. The stud or tooth L strikes against one of the ends of the quadrant-recess M in the upper edge of the journalbox 0 at the end of each quarterrotation, and thus the movement of thejournal D is checked. When the signal is in one position the corresponding ends of the slots N will rest against the shaft H, and when the journal makes a quarter-revolution the opposite correspondin g ends of the slots N will rest against the shaft. The shaft H thus forms an additional check for the rotary movements of the journal D. The shaft H can be rotated by means of electricity, or by mechanical devices, or by means of the chain P, as shown. If this chain overbalances on one side of the pulley O, the weight of the overhanging part of the chain will be sufficient to rotate the pulley O in the direction toward the side from which the chain hangs. This overbalancing part of the chain not only rotates the pulley O and operates the signal, but also looks the samein place, either for the lower weight will always show the same 2 assess color as the signal that can be seen from the tracks. For instance, it the wings F are in the position shown in Fig. 1, the red signals can be seen from the tracks, and the weight Q which is colored red, will be lowered. If the journal D is rotated a quarter-revolution, the white signals will show and the weight Q, which is colored white, will be lowered.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a railroad-signal, the combination, of a rotary carrier, a tubular arm or bracket, in the end of which said carrier isjournaled, and a shaft for rotating the carrier, passing through said arm, substantially as and for the purpose set forth.

2. In a railroad-signal, the arm A, constructed with a vertical journal-box, O, at the end, substantially as herein shown and described, and for the purpose set forth.

3. In a railroad-signal, the combination, with the tubular arm or bracket A, provided with the journal-box U and the hollow journal D of the carrier E, of the lantern Gr, provided with the aperture T in bottom, fitting over the upper end of the said hollow journal, substantially as and for the purpose set forth.

4. In arailroad-signal, the combination, with the tubular arm or bracket A and the signal- I carrier E, of the journal D, provided with the slots or apertures N, and the shaft H, passing longitudinally through said shaft, substantially as and for the purpose set forth.

pulley 0, and the overbalancing chains P, of

the signal-carrier E, provided with the slotted journal D and the rack K, substantially as and for the purpose set forth.

7. In a railroad-signal, the combination, with the carrier E, provided with the rigid signalwings I, of the removable signal-lantern G,

supported upon the carrier between the said wings, substantially as and for the purpose set forth.

8. In a railroad-signal,the combination, with the tubular arm or bracket A, provided with the journal-box 0, having its upper end provided with the recess m, of the rotary carrier E, journaled in the said box and prot'ided with the tooth L, substantially as and for the purpose set forth.
